Go to the log path that was given and see what the actual error is. Given the error message it seems like it was having an issue installing a component which means you'll have to go to look at the component's log file. The setup log should give you more information.
First thought is a bad file. Have you considered downloading the file again?
can you help me ? please 84020-summary-laptop-20210402-220111.txt

You should be very careful about posting setup logs like this. They often contain sensitive information that anyone can see.
Looking at the log it appears the underlying issue is that the setup couldn't connect to WMI running on the machine. However the setup log indicates the error file is sql_engine_core_inst_cpu64_1.log so that may have more information.
If it is indeed a WMI issue then first make sure the WMI service is running. If you have a previous SQL installation you might also consider repairing it first. You might also consider installing the SQL WMI provider manually first as mentioned here.
Of course ensure that your anti-virus isn't blocking the setup and ensure any Windows updates are installed and you've rebooted before running the SQL setup.

Hi @Binh Truong ,
> 2021-04-02 22:01:30 Slp:The MOF compiler could not connect with the WMI server. This is either because of a semantic error such as an incompatibility with the existing WMI repository or an actual error such as the failure of the WMI server to start.
Suggest you do a manual cleanup for previous failed installation and then reinstall it.
Refer to the similar thread Installation problem with SQL Server 2017 (Error 1639) and SQL Server Installer says: MOF compiler could not connect with the WMI server.
